Error handling

[tsloughter]

There are some details in the spec about error handling https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/error-handling.md

I think we may want to use telemetry to signal certain types of errors for the user to handle but I haven't looked at it closely enough to say for sure yet.

Thoughts?

Maybe we can use the logger backend to do such a thing?

@wingyplus there is meant to be attachable error handlers, so I think telemetry fits. It could be optional and just log by default though.

If I understand the Java example correctly, then we can just use Erlang's logger and call it a day, as it supports all we need. Maybe with some helper functions for attaching the filters.

Sound interesting. I just thought that we already use logger, that would be easier to do this. And there is needs to add telemetry execution in the code before doing this if we want to go to telemetry way?

If I understand correctly, we can add logger backend and trap error level and setting the filter on top of the backend.

Better, we can use domain filtering for that.

I made a ticket for adding the domain to all logs: https://github.com/open-telemetry/opentelemetry-erlang/issues/427
